Key Attributes
- Corrosion Resistance: Superior performance in chloride-rich environments (e.g., coastal areas) due to duplex microstructure (austenite + ferrite).
- Durability: High resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC).
- Recyclability: 100% recyclable, aligning with circular economy principles.
- Surface Options: Zinc plated vs galvanized vs stainless steel coatings available for enhanced protection.
Manufacturing Process
- Solution Treatment: Heated to 950–1200°C followed by rapid cooling to optimize microstructure.
- Cold Rolling: Precision-controlled to achieve uniform thickness and surface finish.
- Quality Inspection: Ultrasonic testing (UT) and eddy current testing (ECT) ensure defect-free plates.
Technical Explanations
Tensile Strength
The tensile strength of Eco-Safe stainless steel (≥620 N/mm²) exceeds industry standards, ensuring structural integrity under heavy loads. This property is critical for railroad ties and grids subjected to dynamic stresses.
Bending Strength
With a yield strength of ≥450 N/mm², the plates resist permanent deformation under bending forces. The duplex structure enhances toughness, making them ideal for curved or welded components.
Identification & Marking
Plates are laser-marked with:
- Grade (e.g., 301 stainless steel plate, S22053)
- Heat number
- Thickness and dimensions
Compliance with NB/T 20007 and GB/T 4237 ensures traceability.

Stainless Steel Corrosion Causes
Despite high corrosion resistance, localized rusting may occur due to:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel).
- Surface Contamination: Iron particles or grease during fabrication.
Regular cleaning and passivation mitigate these risks.
